TECHNICAL FIELD

The present invention relates to an ethynylphenylamidine compound or a salt thereof, a method for producing the same, and an agricultural and horticultural fungicide.

BACKGROUND ART

Various compounds with a fungicidal activity for agricultural and horticultural use are known as compounds having an amidino group on the phenyl ring. Many of these compounds have a substituent in the para position of the amidino group, and the substituent is bonded via a heteroatom (oxygen, sulfur, or nitrogen) (see Patent Documents 1 to 10). However, the fungicidal activity of these compounds is insufficient.

There is also reported a compound having a substituent in the above-mentioned para-position directly bonded to a carbon atom without a heteroatom (see Patent Document 11). However, the compound of Patent Document 11 shows an excellent fungicidal activity when used at a high concentration, but has an insufficient effect in practical use as an agricultural and horticultural agent (see Comparative Test 1, described later).

Generally, long-term use of fungicides has recently led to the emergence of drug-resistant fungi. Accordingly, control by conventional fungicides, such as benzimidazole agents, has become difficult. There is thus an urgent demand for the development of a new type of drug that has a fungicidal activity not only on drug-sensitive fungi, but also on drug-resistant fungi.

Test Example 2 Test of Preventive Effect on Cucumber Gray Mold

An aqueous solution of Sorpol 355 (produced by Toho Chemical Industry Co., Ltd.)

The test solution (4 ml) was sprayed to 1.2-leaf-stage cucumber seedlings (type: Suzunari Suyo) planted in a 7.5-cm-diameter pot using a spray gun. After air-drying, the cotyledon of the cucumber seedlings was cut and placed in a plastic case lined with wet kitchen paper. Subsequently, 50 μl of a spore suspension of gray mold (Botrytis cinerea; 1×10⁶ spores/ml) was added dropwise to the center of the cut cotyledon, and an 8-mm-diameter paper disc was placed thereon. Further, 50 μl of yeast-glucose liquid medium was added dropwise, and the resultant was allowed to stand in a thermostatic chamber (20±2° C., 24D, humid state).

Test Example 5 Test of Preventive Effect on Wheat Powdery Mildew

An aqueous solution of Sorpol 355 (produced by Toho Chemical Industry Co., Ltd.) (100 ppm) was added to an acetone solution of the compound of the present invention to prepare a test solution (the content of the compound of the present invention: 500 ppm). The test solution (4 ml) was sprayed to 2-leaf-stage wheat seedlings (type: Shirasagi-komugi) planted in a 7.5-cm-diameter pot using a spray gun. After air-drying, the seedlings were inoculated with wheat powdery mildew (Erysiphe graminis) conidiospore. The seedlings were allowed to stand in a thermostatic chamber (18° C., 12 hours, fluorescent lamp illumination). Seven days after inoculation, the degree of development of the disease was examined, and the preventive value was calculated by the following formula:

Test Example 6 Test of Inhibition of Growth of Wheat Scab Mycelium

Wheat scab (Microdochium nivale) strains were cultured in a potato-dextrose agar (PDA) flat medium at 25° C. The PDA medium was dissolved in an autoclave (110° C., 3 minutes), dispensed into test tubes in 15 ml quantities, and subjected to high-pressure sterilization in an autoclave (120° C., 15 minutes). The test tube containing the medium was cooled to 50° C., and the compound of the present invention was added so that the final concentration was 10 ppm. The resulting mixture was poured into a petri dish (a shallow Nissui P dish). After solidification of the medium, a 5-mm-diameter mycelial disk was implanted from the tip of bacterial flora grown in the above-mentioned petri dish, and cultured at 25° C. for 2 to 3 days. Thereafter, the growth length of the mycelium was measured, and the inhibition rate was calculated in comparison with the untreated sample.

Test Example 7 Test of Effect on Cucumber Powdery Mildew Vaporization Properties

A 10-mm square piece of aluminum foil was attached with a double-sided tape on the first leaf of cucumber planted in a 7.5-cm-diameter pot. Then, an aqueous solution of Sorpol 355 (produced by Toho Chemical Industry Co., Ltd.) was added to an acetone solution of the compound of the present invention to prepare a 100 ppm drug solution (the content of the compound of the present invention: 100 ppm). The drug solution was added dropwise in 50-μ amounts using a micropipette. After air-drying the drug solution, the leaf was inoculated by spraying with a spore suspension of powdery mildew (Sphaerotheca cucurbitae). Seven days after inoculation, the diameter of a disease development inhibition circle on the cucumber first leaf was measured. The appearance of necrotic lesions on the leaf was examined in comparison with the untreated plot. There was judged to be a vaporization effect when an inhibition circle having a diameter of 2 cm or more was formed around the aluminum foil.
